The masses of four objects were measured during a physics experiment. The first and the last each had a mass of 41.918 g. The second and the third objects each had a mass of 24.83 g. Find the total mass of the four objects. Write your answer in scientific notation.

Question

anonymous · Answer

$$TotalMass=M_1 + M_2 + M_3 + M_4$$
and the answer in scientific notation will require you to have only 2 digits after the decimal place, because 2 is the least number of digits after the decimal from the given masses
